Belt Grinder Video Demonstrations

Gardner Knives has been a full-time business in Adelaide for the past 12 years, with workshops and high-end knives. When we started our business, I was determined to start off with the best belt grinder on the market. I remember seeing Radius Master on the New Inventors, years previously, and was intrigued. Not only have I used the awesome Radius Master over the last 12 years, but all our students use them on a daily basis. I tend to give grinders a hard time and I only have one word to say “Indestructible”. So for anyone, particularly in the knifemaking world, if you don’t have a Radius Master or two in your workshop, you’re missing out.

The Radiusmaster II is the latest creation from the inventive mind of John Price. The original Radiusmaster was a innovative machine with five different wheels on one belt. John was recognized on the ABC television show “The New Inventors” for his invention. John has taken on board much of the feedback from the original Radiusmaster and made some performance improvements in the second version.

I was fortunate enough to pick up two of the new Radiusmaster I l’s from John’s factory in Sydney. What an amazing workshop! John works with a small staff in making each of the machines onsite. His equipment and jigs are fascinating – presses and benders, mill, lathes and all kinds of jigs and fixtures to make the parts. Especially interesting was the old Radiusmaster on a 45 degree angle used for grinding the rubber wheels to size. A platen holds the wheels square against the belt, but the belt drifts across the wheel, ensuring no one part gets too hot to melt the rubber. You can see the man’s inventive brain hard at work in the shop.

We originally saw your Radius Master on the New Inventors program. Being very impressed we purchased one immediately and it really has proven to be one of the most useful pieces of plant. The Radius Master is a superbly designed and most versatile piece of machinery; we use ours for component finishing, but its finest hours have been with our tool making. Some fantastic jigs and press tools have been made very efficiently with the help of your brilliant machine.

We can go to it 50 times a day!

Great to see Australia can still lead the way in design. We wish you a great future.

Cheers and thanks from all at Kilmartin Automotive Sheetmetal.
